Function and usage
The GBPI model W320 has two test chambers with two separate sensors, and is a self standing instrument. W320 gives simultaneous test reports, as both the test chambers have separate SENSOR. It measures trace water vapor transmission rates in packaging barrier films. Model W320 ensures the high precision of the testing results with its accurate electromagnetic balance type weighing cell and the circuit handling. It can precisely control the temperature and simulate the humidity. The dual-testing mode (increasing and decreasing weight methods) is initially adopted. Testing curve could spontaneously show the permeation, temperature, humidity and the weight of water permeating cup. It also features auto-judging, auto-outage, and auto-storage of the data’s. The adopted TCP/IP interface make it easy to inspect the running state, controlled by computer through USB. It is designed and manufactured according to the standard
